It's almost certainly just an accident, but does that matter? On the one hand, we have "optimization" of a function that's rarely used to copy more than a handful of bytes, while on the other we have silent data corruption in existing binary applications. How do those two square up to favor the current behavior? -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
